Synthetic Benchmarks: PCMark, 3DMark

PCMark Vantage

PCMark Vantage scales nicely with every bit of clock speed you throw at it.

3DMark Vantage

The CPU test of 3DMark Vantage benefits from faster clock speeds, but the GPU and overall results don’t change much as you increase the CPU clock speed.
